A kind of test I2C communication stabilities method, as shown in fig. 7, this method may include steps of：
Step 701：Predefine testing time 100 times.
The embodiment of the present invention, can be held by the SMC to be measured in Fig. 6 to the I2C interconnection informations in each BMC to be measured
Continuous collection.
Step 702：Pre-set I2C communication stable thresholds 95%.
Step 703：Pre-set time threshold 5 seconds.
Step 704：100 test instructions are sent to SMC to be measured, so that SMC to be measured is receiving test instruction each time
When, corresponding 8 BMC to be measured IP address is acquired by corresponding I2C buses.
Specifically, after sending test instruction to SMC to be measured for the first time, SMC to be measured can lead to according to order from top to bottom
Cross I2C buses BMC to be measured to 8 successively：A, b, c, d, e, f, g, h IP address are acquired, when SMC to be measured this to be measured
After BMC h IP address is acquired, then to SMC to be measured send it is secondary test instruct so that SMC to be measured is again to every
One BMC to be measured IP address is acquired, until completing 100 collections.
In addition, for ease of realizing the process, a time cycle can be also pre-set, such as 30 seconds, so, can be every 30
Second test instruction is sent to SMC to be measured, and without determining whether this is carried out to last BMC h to be measured IP address again
Collection.The time cycle but set should meet SMC to be measured can during this period of time BMC to be measured to 8 IP address enter
Collection is gone, while the accuracy in order to improve test so that SMC is lasting to be acquired, therefore the time cycle should nothing
The IP address limited close to SMC to be measured BMCs to be measured to 8 is acquired the time used.
Step 705：Obtain the collection knot that SMC to be measured is gathered by corresponding I2C buses to each BMC to be measured each time
Really.
For example, by taking the BMC f to be measured in Fig. 6 as an example, such as：
SMC to be measured 1st time is the 6c** of c0 a8 00 to BMC f to be measured collection result by I2C buses；Adopt 9th time
Collection result is 00 00 00 00 00**；The collection result of the 31st time is 00 00 00 00 00**；The collection result of the 98th time
For the 6c** of c0 a8 00.
Step 706：For each corresponding collection result each time of BMC to be measured, judge that current BMC to be measured is corresponding
It whether there is corresponding IP address in current collection result, if it is, performing step 707, otherwise, perform step 708.
By taking corresponding 1st time of the BMC f to be measured 6c** of collection result c0 a8 00 as an example, carry out after decimal system conversion, can
To obtain 192.168.0.108, it is seen then that there is its IP address in the collection result that BMC f to be measured currently corresponding 1st time.
Step 707：Sent to current BMC to be measured and remind instruction, so that current BMC to be measured exports high to corresponding positioning lamp
Level, lights positioning lamp, and when reaching 5 seconds, low level is exported to positioning lamp, extinguishes positioning lamp, reminds external user current
I2C communication connections between SMC to be measured, and perform step 709.
For example, for BMC f to be measured, there is f IP address in the collection result of the 1st time, then can be by being sent to f
Remind instruction (such as lighting positioning lamp 5 seconds) so that f controls coupled positioning lamp 6 to light extinguishing after 5 seconds, 5 seconds, so that
Bright light situation of the test man according to the positioning lamp is obtained, knows in time and accurately that the I2C between BMC f to be measured and SMC to be measured leads to
Letter connection.
Positioning lamp in the embodiment of the present invention be for each node there is provided one, can be with by the state of positioning lamp
Know it is currently that I2C connectivity problems are occurred in that at which node.
Step 708：Alarm command is sent to current BMC to be measured, so that current BMC to be measured exports high to corresponding positioning lamp
Level, lights positioning lamp, reminds the I2C communication disruptions of external user currently between SMC to be measured.
If for BMC f to be measured, can be by treating when 192.168.0.108 is not present in the collection result of the 31st time
Survey BMC f and send alarm command so that positioning lamp Chang Liang, after I2C communication recoveries between BMC f to be measured and BMC to be measured, then
When carrying out the 32nd collection, the phenomenon in above-mentioned steps 707 may just occurs, is such as also bright light 5 seconds.
Step 709：It is determined that the number of the collection result in the presence of corresponding IP address.
For example, SMC to be measured for BMC f to be measured 100 gatherer processes in, have in 96 collection results exist it is to be measured
BMC f IP address 192.168.0.108.
Step 710：According to the current corresponding results judged each time of BMC to be measured, calculate SMC to be measured with it is currently to be measured
I2C communication stationary values between BMC.
According to above-mentioned steps 709, and using calculation formula (1), SMC to be measured and current BMC f to be measured can be calculated
Between I2C communication stationary value
Step 711：Judge whether I2C communications stationary value is not less than 95%, if it is, performing step 712, otherwise, hold
Row step 713.
Due to the default I2C communications stable thresholds 95% of I2C communication stationary values 96% ＞, thus may determine that going out to be measured
I2C between SMC and current BMC f to be measured communicates stable.
For each other BMC to be measured, identical with the above-mentioned principle for BMC f to be measured, here is omitted.
Step 712：Determine that the I2C between SMC to be measured and current BMC to be measured communicates stable, and terminate current process.
Step 713：Determine that the I2C between SMC to be measured and current BMC to be measured communicates unstable.
